Hey there! It's Avery from Rocks Tumbling, and I'm here to help you understand why your tumbled rocks might only polish on the corners. This is a common issue that many rock tumblers face, so don't worry, you're not alone!
When it comes to rock tumbling, achieving a smooth and polished surface on your rocks can be a bit tricky. One of the reasons why your rocks might only polish on the corners is due to the way they are shaped. Rocks with sharp edges and corners have more surface area in those areas, which allows for more friction and abrasion during the tumbling process. As a result, these areas tend to polish more quickly and effectively compared to the flatter surfaces.
Another factor that can contribute to this issue is the type of rock you're tumbling. Some rocks, like quartz or agate, have a crystalline structure that makes them more resistant to abrasion. As a result, the corners and edges of these rocks may polish faster because they are more exposed to the tumbling media.
Additionally, the shape and size of the tumbling media can also play a role in this phenomenon. If you're using small, angular media, such as ceramic cylinders or triangles, they can easily reach and polish the corners of your rocks. However, if you're using larger, rounded media, it might not be able to reach into the corners as effectively, resulting in uneven polishing.
To overcome this issue and achieve more uniform polishing, there are a few things you can try:
1. Rotate the rocks: During the tumbling process, make sure to rotate your rocks regularly. This will help expose different areas of the rock to the tumbling media, allowing for more even polishing.
2. Use different media: Experiment with different shapes and sizes of tumbling media. For rocks with stubborn corners, try using smaller and more angular media to reach those areas more effectively.
3. Adjust the tumbling time: If you notice that your rocks are only polishing on the corners, you can try adjusting the tumbling time. Increasing the duration might give the flatter surfaces more time to polish and catch up with the corners.
4. Check your equipment: Sometimes, uneven polishing can be caused by issues with your tumbling equipment. Ensure that the barrel is properly loaded, the lid is securely closed, and the motor is running smoothly. If you're using a rotary tumbler, make sure the barrel is properly balanced to prevent uneven tumbling.
Remember, rock tumbling is both an art and a science, and it may take some trial and error to achieve the desired results. Don't get discouraged if your rocks don't polish evenly right away. With practice and patience, you'll become a rock tumbling expert in no time!
I hope this helps you understand why your tumbled rocks might only polish on the corners. If you have any more questions or need further assistance, feel free to reach out. Happy tumbling!
